Because who doesn't wanna Scythe-Lock their opponent while having Dragoon and DPE on the field at the same turn?
Mirrorjade is cracked, Chimera is Cracked. This deck is CRACKED.
If you REALLY don't wanna run Scythe- You can drop the 3 copies for Despian Tragedy, Branded Opening, & Edge Imp Chain. It'll still be just as consistent.
